General Definition of (Airport-) Simulation

General Definition of (Airport-) Simulation

Dynamic simulation, unlike static calculations (traditional spreadsheets), becomes particularly valuable when dealing with complex systems like an airport and the airspace. Complexity can arise from factors such as system size, interconnected processes, human-interactions, process variability, or the number of different actors as passengers, aircraft, facilties or vehicles.

Dynamic simulation visualizes the time-based interactions within a system, allowing for the inclusion of stochastic influences. This provides a significantly more accurate representation of system behavior compared to static flow calculations. Certain time-dependent metrics can only be determined using dynamic simulations. Additionally, simulation models can process large amounts of data, such as aircraft or passenger data and flight schedules. 

The animation of passenger flows and vehicle and aircraft movements combined with the graphical representation of results facilitates rapid understanding and communication of system behavior and options for optimisation.
 

Simplified, simulation means:

• Building a model in a computer
• Experimenting with the model
• Drawing valuable conclusions for reality

Typical Phases of Simulation

1. Definition of Questions and Objectives: These determine the scope and level of detail of the model.
2. Process Analysis and Data Collection
3. Model Description: This documents the questions, objectives, scope, processes to be modeled, input data, scenarios, evaluations, etc., and finally the detials of results and deliveries
4. Model Creation
5. Model Validation: This phase ensures that the simulation model accurately represents reality.
6. Simulation Experiments to Analyze System Behavior and generate the relevant KPI
7. Assessement of the results, conclusions and recommendations
8. Documentation

Challenges of Simulation

A common challenge is transferring the insights gained from simulation into implementation. To overcome Simulation-to-Implementation Challenges it is recommended:

1. Strengthen Collaboration: Improve networking between simulation and implementation teams through regular communication and joint meetings.
2. Clear Documentation: Ensure documentation is clear, comprehensive, and tailored to the needs of both technical and non-technical stakeholders.
3. Adapt to Changes: Stay flexible by updating simulations to reflect any changes in preconditions or system configurations during implementation.
4. Highlight Benefits: Clearly communicate the practical benefits of simulation results to drive engagement and commitment from the implementation team.
